I build automation platforms that make database performance benchmarking reproducible at scale. By day, I work with Terraform, Ansible, Kubernetes, and Go at the Dell Innovation Center. By night (well, also by day), I research container interference profiling for my Master's at PUCRS — figuring out why your "isolated" workload is mysteriously 30% slower in production.

Former classical violinist who traded obsessing over intonation for obsessing over p99 latency. The pursuit of mastery carried over — my teammates once called me "The Infra Wizard" during project retrospectives, and I'm still not sure I've lived up to it. 🧙

TL;DR — I bridge academic rigor with production engineering. Bring me your unreproducible benchmark, your flaky CI, your "it works on my cluster," and let's measure our way out.

🛠️ At Dell Innovation Center

Performance & Automation Engineer

End-to-end automation for distributed database benchmarking across Oracle, MongoDB, and PostgreSQL — at scale, fully reproducible.

  • Python + Ansible provisioning (hours → minutes)
  • Containerized HammerDB / YCSB pipelines
  • Production observability: Prometheus + Grafana
  • Custom Terraform providers in Go for proprietary infra
  • Kubernetes-based environment automation

🔬 MSc Research — IntP

Advisor: Prof. Cesar De Rose · PPGCC-PUCRS · 2026–2027

Kernel-level performance interference profiler for containerized environments — answering why noisy neighbors hurt, not just that they do.

  • Multi-variant comparison: SystemTap, procfs, bpftrace, eBPF/CO-RE
  • Reproducible noise injection (CPU, mem, net, I/O)
  • Integration with HDFS / Spark workloads on PUCRS LAD
  • Targeting Linux 6.8+ stable surface
